Appntio inea July 27, 1914. serial No. 853,395'.

To all whom t may concern Be it known that I, JAMES CAssIDY, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Removable Handles for Rock-Shafts', of which the following is a specification. l

kThis' invention relates to aI removable handle which is primarily to be used on 'the rockrshaft ofa sanding device for street and otherrailways. K

The objects ofthe invention areto obtain a removable handleby means of which one or more rock. shafts may be actuated, to operate a sanding device, to discharge sand before one or more of the trucks of an electric or other car, or to the rear of said trucks.

A further object is to obtain .a removable handle by means of which a sanding device may be operated for all the above enumerated conditionsr,

A `further object isto obtain a device of the kind named which can be V.operated readily and quickly, `for any and all the above purposeswhich is notV liable to get out of order, te be broken, or to fail in operation.

A further object is to obtain 'a device which 'is economical vin construction, and readily understood by motor men and other persons requiredto use the same. p.

To those familiar with the operation of electric motor 'cars itis known that at times it is very desirable to discharge sand in front of the forward pair of wheels of the car; that at other times, in making what is known as an emergency stop, it is desirable to discharge -sand in front of more than one pair of said wheels, and in other cases, as where a car is'standing still on a grade, or where it is desired to back a car, it is desirable to discharge sand in the rear of one or more of said pair of wheels. A

I have illustrated a handle embodying this invention, and so much of a sanding device as is required to understand the application of the device thereto, in the dr'awings'aceompanying and forming a part, of this specification; in which drawings Figure l is a top plan view of the device, and ofthe rock shafts of-a sanding device. Fig. 2 is a vertical section lof the device and o`f said shafts. FisA 3 is a hQrZO-ntalisecton, A911 lin@ 3.-.3 of Fig. 2, viewed in the direction indicated b y the arrows. Fig. 4 is a horizontal section, on lineY 4-'4 of Fig. 2, viewed in the direction indicated by the arrows. Fig. 5 is an elevation of the handle, with a part thereof in section. F ig. 5 is a vertical section, on linee-6 of Fig. 5, viewed in the direction indicated by the arrows. Fig. 7 1s a top viewy of the standard of the device. Fig. Sis a side elevation of the upper end of said standard. Fig. 9 is a perspective of a latch forming an element ofthe device. Figlis a perspective of a bolt body and bolt thereon and of a latch engageable therewith.' And Fig. ll is a plan view ofthe upper end of a tube shaft which may be operated by the device.

A reference character applied to designate a given part indicates said part throughout the several figures of the drawing wherever the same appears. l

A is a vertical shaft, to which the device embodying this invention is removably attachable.

B and C, are, respectively, tube 'shafts mounted on, and concentric with, shaft A. Shaft A may be turned independently of tube shafts B, or C.; or it may be turned with ne or both of said tube shafts, as 'desired, by means of the device embodying this inventicn.

D is a pulley on the lo-wer end of shaft Y C,.and d, CZ, are cables on said pulley.

D1 is a pulley on the lower endof tube shaft B; d1, is a cable on, said pulley D1; D2 isa pulley on tube shaft A and cl2, is a cable on said pulley. The several pulleys D, D1, and D2, actuate, by means of cables (Z, all. and (Z2, the valves of corresponding sand boxes, but as said sand boxes and valves form no part c-f this invention the same are not illustrated.

E is a handle, which is provided with hub F, and said hub is provided with a rectangular hole (i), therethrough. The upper end of shaft A is rectangular, and fits loosely in hole f, (shown by broken lines in Fig. 5).

G is a wedge in hole f of hub F, H is a screw threaded bolt which is vattached `to wedge Gr and L isa butteriiy nut on bolt H.

71,1 is a spring to yieldingly hold bolt H advanced. By turning the butterfly nut down on bolt H, spring h1 is retracted and wedge G is raised in hub F, and thereby said hub is rigidly secured on said shaft, A. To remove the handle from said shaft the Y gages with the holeU.

latches, which are yieldingly held in an ad' vanced position by the springs K, L. The rear ends of said bolts are beveled, as at z', j, and M, N are shoulders adjacent to said ends, which are engageable with spring latches O, P, respectively, and when said latches are in engagementwith saidV bolts the bolts are retained in a retracted position, against the resiliency of springs K, L.

C), is a pushV button to spring latch O, an R is a push button to spring latch P. Y

S is a button, or abutment on bolt I, by means of which it may be retracted by the operator,cand T is a like button or handle to bolt J. Buttons S and T, respectively move laterally in slots t, t, when said bolts I, J, move longitudinally.

U is a hole in the upper end of tube B, and bolt I is engageable in said hole and when said bolt is in an advanced position, (in said hole) the movementof the handle E turns said tube.

U1 is a like hole in tube C, and bolt J engages with said hole in the same manner, and for -the same purpose that bolt vI en- 'V is a bolt secured in body V1, and said body is pivotally mounted on screw or pivot handle.

V3 is a tie rod, and V4 is a bell crank and Tie rod Va'connects pivoted body Vl and bell crank V4. f

V5 is the pivot on which bell crank VAi turns, and V6 is' a spring which yieldingly holds said bell' crank and body V1 in position with the bolt V advanced.

W is a hole in standard X, with'which the bolt V is engageable when the handle E is moved into position to turn shaft A so lthat the valves of a sand box, (or other device) are open, or operative. The purpose of said bolt V is merely to hold the handle E in operated position and relieve the operator. When the handle E is to be again put into an inoperative position the handle V4 is moved toward handle E, (Fig. l) and bolt V thereby retracted, or disengaged from hole lV.

Vith the bolts I, J, held in a retracted position by latches O, P, to operate the device the handle E is turned, turning therewith the shaft A. lVhen shaft A and tube shaft B are both to be turned, the push button Q is depressed, before said handle is turned. To turn tube shaft C the button R is forced in, lto disengage latch P, before handle E is turned. To turn shaft A and both tube shafts, (B andrC), pushbuttons Q, R are both forced in to disengage both latches O and P, and handle E is then turned.AV `When handle E is turned the bolt V automatically engages with the hole lV,

tc maintain said handle in its turned position until it-is desired to return said handle to its initial place, when the bell crank V4 is forced toward handle E, thereby withdrawing 'bolt V from hole 14V. g

I claim Y l. A handle having a socket with an in* clined face thereto and a table at the upper end of said socket, a VVwedge within said socket,'said wedge having an inclined face adapted to co-act with said inclined face of said socket, ysaid socket adapted to fit over the squared end of a shaft, a screw threaded shaft pivotally and non-rotatably attached to said Wedge and arranged to extend abutV against said table and said wedge to yieldingly hold said wedge in an inoperative position, and a screw threaded nut rotatably mounted on said bolty and adapted when turned to move said wedge longitudimove said Wedge to secure said hub on said shaft, a plurality of tube shafts loosely mounted on said rock shaft, mechanisms on said handlev andV tube shafts respectively adapted to bind said tube shafts to said hanvthrough said table, a spring arranged to,

dle, said mechanisms comprising, respectively, bolts yieldingly held in an advanced and operative position, means whereby said bolts may be separately retracted to an inoperative'position, means to hold said bolts ina normally retracted position, and means to vseparately release said bolts from said holding means to render said bolts operative to bind a selected tube shaft to lsaid handle.'

3. The combination of a standard, a rock shaft mounted in said standard, a handle on said shaft, a plurality of tube shafts loosely mounted on said rock shaft, interlocking mechanisms respectively adapted to bind said tube shafts to said handle, said interlocking mechanisms respectively comprising bolts yieldingly held in an advanced and operativevposition, means whereby said bolts may separately be retracted, and means to hold said boltsnormally in said retracted position, means to separately release said holding mechanisms, thereby permitting lsaid bolts to be operative, and bind said rock shafts and handle together, and means on said 4standard and handle adapted to engage and hold said handle in a determined position.

4:. The combination of a handle having a hub, a standard, a rook shaft mounted in said standard, means to secure said hub to said rock shaft, a plurality of tube shafts loosely mounted on said rock shaft, mechanisms on said handle and tube shafts'respectively adapted to bind said handle and tube shafts together, said mechanisms respectively comprising bolts yieldingly held in an advanced and operative position, means Whereby said bolts may be separately retracted to an inoperative position, means to normally hold said bolts in a retracted position, and means to separately release said bolts from said holding means and 15 thereby render said bolts operative to bind a selected tube shaft to said handle.
